This weight- 0 a represents a suitable frame-base, from recording wheel is provided with a central which rises, as hereinafterdescribed, vertical shaft or journal 0 the projecting end porframe-pieces, which support or form bearing tions of which bear, as prescribed for the shaft for the weighing mechanism. b, in the crotch of two suitable bearing-wheels 1) represents the power or operating wheel, 0 which correspond with the wheels b and 95 which is mounted,as shown, in the upperporwhich, as prescribed for the latter, have their tion of the frame-work and through which moshafts or j onrnals bearing between bearingtion is imparted to the recording-wheels, as wheels 0 which are supported from short hereinafter described. This wheel I) is provertical frame-pieces 0 The shaft 0 carvided with a short central shaft 1), which prories on one side of the wheel 0 a pinion-wheel [O0 o The outer face of the rim of the wheel 0 is engraved or otherwise made to appear, marks indicating a graduated scale c c is apermanent indicating hand or pointer, which rises from the frame-work and has its upper termination opposite the scale-mark rim of the wheel 0. The periphery of said wheel a is provided with inclined teeth 0 with which are adapted to engage the lower ends of the pawls 11 d represents a shaft the ends or hearing portions of which are supported, as shown, upon bearing-wheels, as prescribed for the shafts c b. This shaft (Z extends from a point near the forward side of the wheel 0 outward in a line parallel with the shaft 0 and carries thereon a gear and record wheel (1'. lhis wheel (1' is somewhat smaller than the wheel 0, and as prescribed for the said latter wheel has its rim-face marked with a graduated scale, (indicated at (1 The teeth of the gear-wheel d mesh with the teeth of the pinion c. The wheel (1 is provided, as prescribed for the wheelc, with a stationary indicating-hand diwhich rises from the framework and which has its upper termination opposite the scale-marks on the rim of said wheel. Between the wheels (1 and c the shaft d carries, as shown in Fig. 2, a pinion d", the teeth of which mesh with the teeth of a large forward gear and record wheel d, which is provided with graduated scale-marks d. The central shaft or journal of the wheel d bears, as indicated at (F, upon bearing-wheels which correspond in construction and arrangement with the wheels c This wheel (1 is also provided with a stationary indicatinghand (P, which corresponds in form and arrangement with the hands (Z 0 6 represents a record and ratchet wheel, which is carried upon a shaft 6, the latter being journaled, as prescribed for the shaftcarrying wheels hereinbefore mentioned, on the opposite side of the operating wheel from that on which is located the wheel 0 This Wheel 6 is of such size and arrangement as to admit of the ends of two or more pawls 6 which depend from the crank U of the shaft 1), engaging with the teeth on the periphery thereof. As shown in Fig. at of the drawings, the outer face of the rim of the wheel e is provided with graduated scale-marks e and a stationary indicator-hand ciwhich projects in front of said scale-marks. The normallyupper portion of the power or operating wheel I) is provided on its rim with segmental racks f, with which engage the teeth of a pinionf, which is carried on a vertical shaft or spindlef This spindle has its lower end pivotally supported in a suitable bracket f, from which said spindle rises to a point above the wheel I). The upper end of the spindle f supports, as shown in the drawings, a suitable check-tube f which from its supporting-point are inclined outward and downward vertical bends, (indicated at f f represents a suitable counter-balance, which projects from the spindle f in that side thereof, which is opposite the tubef Rising from the base a-are suitable standards 9, between the upper portions of which is supported an annular check-box f. This ring-shaped box is, as shown in the drawings, provided with radial partitions, which will result in the formation of a series of compartments f arranged in a circular form in the box. The annular box'f is of such size and location as to bring the lower termination of the tubef immediately above and adjacent to the compartmentsf Affixed to the shaft 1), adjoining the hub of the wheel, is the upperend of adownwardly-extending weight-arm t, which, extending downward through a suitable opening in the base a, carries on its lower end a weight i A pawl m, pivoted to the frame beneath the wheel 0 and adapted to engage with the teeth of the latter, will prevent the backward movement of the train of wheels.

The operation of my improved weighing mechanism is as follows: The load of ore or other substance to be weighed is suspended in the usual or any desired manner from the beam-rod 0 thus resulting in a downward movement of the forward end of said beam and in an upward movement of the rear end thereof. This upward movement of the beam will result through the connection of the rod 0 and strap 0' and the connection of the latter with the wheel I) in a partial rotation of said wheel. This rotation of the wheel Z) and its shaft 1) will result in the upward movement in the arc of a circle of the crank 11 and in the engagement of the pawls b with the higher teeth on the wheel a. This movement of the shaft 1) will also result in the upward movement in the arc of a circle of the weight '6 lVhen the scale-beam is released from the weight of the platform thereof, the upward movement of the outer end of said beam will result in connection with the consequent downward movement of the weight t in turning the power-wheel b to its normal position and in a consequent downward movement of the crank 11 This movement of the crank 12 will result through the engagement of the pawls b with the teeth of the wheel 0 in partially rotating said wheel. The parts thus moved are so adj usted and arranged with relation to each other and with relation to the scale upon the wheel 0 as to result in the stationary pointer 0 being brought opposite that scalemark which indicates the weight in tonnage or otherwise of the load previously suspended from the scale-beam. It is evident that the amount thus registered or indicated upon the rim of the wheel 0 will be regulated by the extent of movement of the pawls b and that this movement of said pawl is regulated by the extent of movement or rotation of the wheel Z7. As each successive load of ore or other material is thus weighed, it will be seen that the weight amounts will be added and the additions indicated by the indicating-hand 0 In order to carry and retain the weight amounts beyond those which might be indicated byone complete revolution of the wheel 0 I employ a wheel (1', which, owing to its gear connection with the pinion of the wheelshaft c is driven at much slower speed than the Wheel c. This wheel (1 will operate to indicate the weights taken after the wheel 0 has made a number of revolutions. In order to still further recerd or register the weights taken, I have employed the wheeld which, being larger and traveling at a speed less than the wheel (1, is capable of showing the total of the accumulated weights of the wheels 0 (1 after the latter have made many revolutions. In this manner the pointer of the wheel (1 might indicate for a month or even greater period of time the amount of coal or ore weighed within said period.

My method of ascertaining the separate weights of a car and the cargo to be placed therein is as follows: The car or other receptacle being placed upon the scale-platform, it is evident that the partial rotation of the shaft b will result in a corresponding partial rotation of the crank b and in the elevation of the pawls (2 When the scales are relieved from the weight of the car or other receptacle, the wheel 6 will be driven by the pawls e such distance as to indicate by means of the hand 0 that scale-mark of the wheel c which shows the weight of said car. The pawl 8 may then be lifted or otherwise disengaged from the teeth of the wheel 6 and the latter turned back by hand until its indicatinghand is at its starting-point. The car being returned to the scales and loaded, the independent car-weight, taken as hereinbefore described, can be deducted from the total weight of the car and cargo to ascertain the amount of the latter. At each partial rotation of the power-wheel b it is evident that through the connection of the pinion f with the teeth f of said wheel the spindle f is rotated sufficiently to carry the outer end of the tube f which is supported thereby, in the are of a circle. A common method of keeping account of the amount of coal mined by each miner or set of miners consists in providing each of these miners or set of miners with numbered checks indicating the number of the miner or set to which he belongs. For the sake of illustration I will suppose that miner No.7 has filled a car with coal and his check bearing his number has been previously hung in the car. hen the coal is dumped into the weighing-hopper, which is supported by the scale beam, the dumper removes the check from the car and drops it into the tube f Owing to the fact that said tube has through the action of the wheel 19 been carried opposite the proper pocket or compartment f of the annular box J, the

check containing the number of the miner is deposited in that pocket or compartment which represents the weight of the coal in the hopper. In this manner each minor or set of miners is given credit for the coal-weights indicated by the compartments in which are found the checks.

In constructing my device it is evident I may number the scale-marks upon the wheelfaces in any desired or proper manner and that the pockets or compartments of the annular check-boX may be numbered to indicate different weights. It will be observed that the construction and arrangement of parts herein shown afford not only a means of retaining the gross weights taken by the scales during a long period of time but a convenient and accurate means is also supplied for indicating the weights of coal or other substances for which the miners are entitled to credit. It will be observed that the means herein shown for mounting the various wheels and running parts of my machine are such as to prevent the evil results of great friction, and that my machine is otherwise constructed in a simple, neat, and reliable manner.
